Objective:
The objective of this work will be to calibrate and validate the APEX model for the Lake Plain soils of the Maumee River Basin.

Approach:
Published data from the Lake Plain region with information about hydrology and nutrient loss pathways will be summarized. Specific field research may be advanced on priority research questions to assist with model calibration. The APEX model will be calibrated and validated given the best available dataset, in order for NRCS to utilize the model on NRI datapoints within the Maumee basin.
